Our experience working with Keuthen AG has been consistently professional, reliable, and solution-oriented. As a modern, digital company, having a strong and innovative system partner is of paramount importance to us. That’s exactly what we have with the Keuthen AG team by our side! Inquiries are handled quickly, problems are solved pragmatically, and working together is always a pleasure. We highly recommend them!

“An exceptionally competent and warm-hearted professional” I would like to express my highest regard for Ms. Keuthen. Her professional guidance is characterized by a remarkable calmness, patience, and warmth that one rarely encounters in this form. She takes the time to truly listen and manages to explain even complex topics in a clear, structured, and solution-oriented manner. I was particularly impressed by her reliability and the care with which she guides you through every single step. With her, you not only feel excellently supported professionally, but also seen and valued as a person. Ms. Keuthen combines competence, empathy, and a genuine passion for her work—and that is exactly what makes working with her so pleasant and trusting. Highly recommended!

As the managing director and tax consultant of HSP STEUER Michael Huber Steuerberatungsgesellschaft mbH, I recently outsourced the installation of DATEV UNTERNEHMEN ONLINE for my clients completely to KEUTHEN AG. They set this up for our clients independently, reliably and on time. For me a clear relief and a recommendation... ABSOLUTELY TOP...
Comment by Keuthen AG
Thank you very much, Mr. Huber, for your trust and the great feedback! 🙏 The complete outsourcing of the DUO setup is the right step for tax firms - we are all the more pleased that you feel relieved by our support. The fact that you rate our reliability and adherence to deadlines for your clients as "absolutely top" is a real compliment for our entire team 💚 We very much look forward to continuing to work with you - with commitment, personally and in partnership. Your team at Keuthen AG

We are 100% satisfied with the support provided by Keuthen AG. Mrs. Keuthen is a very competent and nice person with whom the training is always fun and very easy to understand. Since the training, working with our DATEV is even more fun, because here you get all the possibilities of the program explained and shown in detail. We can absolutely recommend Keuthen AG.
